AMOS E. WHIPPLE, OF WI-IITINSVILLE, MASSACHUSETTS, ASSIGNOR TO WHI'IINMACHINE VV'ORKS, OF WHITINSVILLE, MASSACHUSETTS, A CORPOBATION OFMASSACHUSETTS,

SPINDLE-DBIVING MECHANISM.

Specification of Letters Patent. 'Patented Mar. 12, 1918.

Application filed June 1, 1916. Serial No. 101,196.

T 0 all whom it may concern:

Be it known that I, Amos E. WVi-IIPPLE, a resident of lVhitinsville, inthe county of lVorcester and Commonwealth of Massachu setts, haveinvented a certain new and useful Improvement in Spindle-DrivingMechanisms, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

This invention relates to an improvement in spindle driving mechanismsin which the spindles are driven from a rotating cylinder by means ofendless bands or tapes having frictional contact with the peripheralsurfaces of the cylinder and spindle whirls, a group of two or fourspindles usually being driven by each tape. 6

The object of my invention is to provide an improved construction of thetension pulley hanger whereby chafing of the driving tapes against thehanger is avoided and also the hanger is so designed that it may beremoved without cutting the tape.

Another and important'object is to provide simple means for preventingdamage to a tape due to its slipping from its pulley and becomingentangled with adjacent tapes, or winding about the cylinder.

The novel features of my invention will be hereinafter described, andparticularly pointed out in the following claim.

Referring to the drawings:

Figure 1 is a transverse sectional elevation of such parts of a spinningor twisting frame as are necessary to show the application of myinvention.

- Fig. 2 is a plan view of the same showing a group of spindles, theirdriving tape and its slack take-up. r I

Fig. 3 is a front elevation of binder pulley hanger showing a preferredform of the tape retainer.

Fig. 4c is a side view of same.

In the accompanying'drawings, the spindle rails 1, the spindles 2, theirwhirls-3, the driving tape 4, the tension pulley 5, and the tape drivingcylinder 6 are all of the usual type in common use in spinning andtwisting frames. In the usual type of frame the binder or tension pulley5 is journaled in times in the tape.

bearings fitted in the arms of an inverted U shaped'hanger. With thisconstruction the tape is subjected to excessive wear due to chafingagainstthe arms of the hanger:

Another objectionable feature is thenecessity of cutting the tapewhenever it is de: sired to. remove the hanger. my improved hanger theseobjectionable features are eliminated. 1

In my improved constjuction the binder pulley 5 is journaled in bearings7 fitted in the hook-shaped hanger 8 which is removably connected to theweight arm 9 swinging on rod 10 so that the leverage exerted by theweighted arm takes up the slack in the tape thus maintaining an eventension at all By the use of To facilitate the removal of a hangerwithout cutting the tape the hanger is so designed that the binderpulley is held in two bearings, one in the main leg of the hanger, andthe other in an arm of a hook-shaped extension 11 of the main leg inangular relation thereto. The angularity of the extension is so designedthat the bottom of the hook is located between the receiving anddelivery paths of the tape as it passes about the binder pulley and thehanger is easily removed.

In case a tape should accldentally run oft its pulley a guard 16,'Figs.3 and 4, prevents it from becoming entangled with adj acent tapes andthe resulting damage thereof.

"This guard consists of an upwardly extending finger located on thehooked extension of the hanger and so situated that the tape on slippingfrom its pulley is caught ina pocket formed by the side of the pulley,top of the pulley bearing and the guard.

I claim:

In a spindle driving mechanism, the comof spindles, a tape fortransmitting motion bination of a driving cylinder, a plurality fromcylinder to spindles, a tape binder pulley, a hooked-shaped hanger forthe same, and'a tape guard consisting of an upwardly extending fingerlocated on the hooked extension of the hanger andsubstantially parallelwith the main leg of hanger.

In testimony whereof, I have signed this specification.

. AMOS E. WHIPPLE.
